By turning the crank arm 30, the spring 31 tension to give the according to the amount and Weight of paper placed thereon.

As the uppermost sheet of paper is drawn from the pile by the feed roll 19, the spring 31 acts in'rmediately to correspomlingly elevate the table so that the following sheets I will be successively acted upon by said iced roll. It will be apparent that the parallel levers 26 and 27 by reason of their pivotal connection with the machine frame and the table will maintain the horizontality oi the table under all conditions of the latter.

llaving thus described the invention, what is claimed as new, is:-

1. in a rotary duplicating machine, the

combination with a stencil-carrying drum; of

a paper supporting table; a paper l'eed roller arranged above the table; means controlled by the drum, operating intermittently to refeed roller and cause the volve the paper latter to advance the uppermost sheet toward the drum, and means for yieldingly The \l-shaped shoulders 33 may be formed integrally with the pendent @supporting and urging the table upward, comprising parallel levers interposed between the machine frame and table, a shaft, and a spring encircling said shaft and having one end connected thereto and the free end thereof operating in an upward direction against the table.

2. In rotary duplicating machine, the combination with a stencil. carrying drum; of a paper supporting table; a paper feed roller arranged above the table; means controlled by the drum, operating intermittently to revolve the paper feed roller and cause the latter to advance the uppermost sheet toward the drum, and means for yieldingly supporting and urging the table upward, comprising parallel levers interposed between the machine frame and table, a shaft, a spring encircling said shaft and having one end connected thereto and the free end operating in an upward direction against the table, and means for turning and holding said shaft to regulate the tension ol' said spring. 4

In testimony whereof we allix our signatures in presence of two Witnesses.
